About

EUC & Workplace Technology Lead with 12+ years of experience delivering enterprise IT services for 1,500+ users in a global airline environment across corporate offices, airports, and remote workforces. I specialize in End User Computing, Microsoft 365, Intune, device & identity management, AV/VC systems, and VIP support — building secure, reliable, and highly productive digital workplaces. In my recent role, I led EUC and workplace IT operations, owning P1/P2 incidents, SLA performance, ServiceNow operations, and end-user experience while coordinating with global infrastructure, security, and application teams. I bring strong hands-on expertise in Intune, Entra ID (Azure AD), Conditional Access, device compliance, Autopilot, and endpoint security — not just configuring tools, but running large-scale enterprise environments. I am currently seeking opportunities as an EUC Lead, Workplace Technology Lead, IT Operations Lead, or Digital Workplace Manager where I can combine deep technical ownership with leadership and service delivery excellence.
